Slow-energy hadrons in extensive air showers

Investigated has been the low-energy hadronic component of the extensive air showers with the number of particles working out to N=5x103-5x105. The experiments have been staged at 1,850 m above the sea level at the Elbrus cosmic ray laboratory. The experimental installation is composed of the Wilson chamber in the magnetic field and a hodoscopic device. Obtained have been the integral energy spectra of the low-energy hadrons and the dependence of the nuclear-active particle number on the number of particles in the extensive air showers. The number of the nuclear-active particles is proportional to the number of particles for the showers whose power exceeds 105
